I'm thinkin about tryin some heritage carbons.  I shoot a gamemaster 2  45@28. I draw 28". Should i try 150s or 250s? 125gr head

150's.

I think the 150s would be fine might even try the 90s. I use the 150s out of my Bears Paws recurve 54lbs at 28 inches fly great good arrows. TD.

You will need a lot of weight up front to get the 150s to fly right. I shoot them out of my 52-55# recurves cut to 29.5"s and need 175 up front for perfect flight/ Shawn

thanks for the input

Heritage CX90 is what I use with my 42# Treadway. I still use 250gr up front. At your draw length it might work. My limited experience tells me that 150s would be too stiff. I would rather be on the weak side than stiff.
Shawn knows his stuff when it comes to carbons. He is the one that got me on the right track with carbons.

150s

I am shooting 150s with 200 grains up front out of my 42 lb@28  Banshee. They are 30 inches long. I draw my bow 29 inches so I figure I am shooting 45 Lbs. They bare shafted perfect.

I was thinkin that i should leave em long and maybe add 50 grain inserts to soften em up
